    摘要： A marine vibrator (19) that in a particular embodiment includes a substantially elliptically shaped outer shell (2), a driver (8) having a first and second end, at least one outer spring connected between the first end (13) and the second end (13) of the driver, and at least one inner spring (4) connected between the first end and the second end of the driver. One or more masses (7) are attached to the inner spring (4). At least one transmission element connects the outer spring and the outer shell. The outer and inner springs and the masses attached to the inner spring are selected to generate a first resonance frequency and a second resonance within the frequency range between 1 Hz and 300 Hz.

    摘要： The present invention refers to a magnetostrictive actuating device provided with at least one channel for a cooling medium. Said magnetostrictive actuating device comprises an elongated rod (3) of a magnetostrictive material, a magnetic coil (5) arranged around the rod (3), a permanent magnet member (6, 7) adapted for magnetizing the rod (3) together with the coil (5), and a magnetic return conductor member (4a, 4b, 8a, 8b, 9) which together with the rod, the coil and the permanent magnet member form a closed magnet circuit, and at least one cooling channel being adapted to conduct a cooling medium for cooling the actuating device. The cooling channel comprises an inlet section, an outlet section, and an intermediate section (12), whereby at least one of the inlet section and the outlet section extends at least party in said permanent magnet member (6, 7).
